After a skiing accident that broke the patient's tibia and fibula, the left leg was put in a long-leg plaster cast. Even though the cast is still damp, the patient claims it is hot and uncomfortable. The sense of heat most likely means which of the following?
It is natural to experience the cast as hot and painful because heat is produced while it is drying. The patient needs to be reminded to make sure the cast is left exposed until it has dried completely (between 24 and 48 hours). The leg should be maintained elevated to reduce swelling, but it can also be supported by a pillow to assist avoid the cast from drying out in an unintended form. Every two hours, the patient should be rolled over so that air can circulate around the cast and dry evenly.
The central venous pressure (CVP) of an adult patient is being monitored, and the pressure is decreasing. Which method is used to confirm hypovolemia?
A fast fluid infusion of 250 to 500 mL may be administered because hypovolemia is the most frequent cause of a decline in CVP. If the pressure begins to drop again after ten minutes, hypovolemia is likely the cause. Always utilize serial readings to confirm an increase or reduction. The right atrium, right ventricle, and blood flow back into the heart are all evaluated using the CVP, which is the pressure in the superior vena cava close to the right atrium. Depending on the method of measurement, the normal ranges for CVP are 0 to 8 cm H2O or 2 to 6 mm Hg.
What are the main symptoms of a broken mandible?
Malocclusion and ecchymosis of the mouth floor are the main symptoms of mandibular fracture. There can be a gap between the teeth. Blunt trauma causes the majority of wounds, and numerous fractures may be present. Although bleeding may happen if the fracture tears an artery, such as the inferior alveolar artery, bleeding from blunt injuries is uncommon. Most of the time, pressure application, fracture reduction, and/or local anesthetic with epinephrine are enough to stop the bleeding.
Which type of concussion would be considered in the case of a soccer player who was struck in the head by a ball and experienced temporary bewilderment for ten minutes after the injury before it went away?
Grade 1 (Mild): Temporary confusion without coma, and symptoms go away in about 15 minutes.
Indications of Cushing's triad (bradycardia, hypertension, and abnormal, irregular respirations) may be a marker of when evaluating the ABCDEs of a patient with traumatic brain injury.
Indications of the Cushing's trifecta (bradycardia, hypertension, and abnormal, irregular respirations) could be a marker of brainstem herniation while evaluating the ABCDEs (Airway, Breath/ventilation, Circulation, Disability, Exposure/environmental control) of a patient with a traumatic brain injury. The most frequent cause of herniation is elevated intracranial pressure, which impairs oxygenation and blood flow to the brain.
A 30-year-old patient with an ipsilateral distal radius fracture and elbow dislocation complains of excruciating forearm pain. Analgesia does not relieve the pain. What should the nurse be on the lookout for?
An early symptom of compartment syndrome, which is typically brought on by bleeding into the tissue, is severe, growing pain that is not eased by analgesia and is localized distal to the injury (in this case, the forearm). Upon examination, the compartment feels tight, and passive muscular stretching may cause pain. Paraesthesia and hypoaesthesia could develop in patients. Finding a pulse below the injury should not lead the nurse to believe that compartment syndrome is ruled out because motor weakness and vascular insufficiency are late signs.
Following a tractor accident, a 27-year-old patient is brought into the emergency room with an open, contaminated fracture of the tibia. Which of the following details should you particularly try to get from the patient?
For all open infected wounds, the time since the most recent tetanus vaccine is particularly crucial. However, if the patient is not immunized, has had fewer than three immunizations, or is unsure about immunization, then the patient should receive both the tetanus toxoid and tetanus immune globulin because tetanus toxoid does not immediately confer immunity while tetanus immune globulin provides temporary immunity right away. Patients who have had three or more immunizations.
